CLAMP FOR FENCE-WIRES.

To all whom it may concern:

Be it known that we, JOHN T. GRAYsoN and JAMES I. HENTZ, residing atBlountstown, in the county of Calhoun and State of Florida, haveinvented certain new and useful Improvements in Clamps for Fence- Wires;and we do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to clamps for holding the ends of fence-wires, sothat all the wires can be stretched and tightened simultaneously; and itconsists in the novel construction and combination of the partshereinafter fully described and claimed.

In the drawings, Figure l is a side view of the clamp. Fig. 2 is an endview of the clamp. Fig. 3 is a plan view of the clamp. Fig. 4 is across-section through the clamp, taken on the line -V in Fig. l.

A are the wires of a wire fence.

B and C are two clamping-bars between which the end portions of thewires A are inserted.

The bar B is provided with eyes D having screwthreaded stems al' andnuts d for securing them and adjusting them. The eyes D can be madecontinuous or in the form of hooks, as desired, both forms being shown.The bar C is provided with slots c, and the eyes D are arranged toproject partway through these slots.

E are two bearing brackets secured to the bar C. One of these bracketsis preferably secured by a thumb-nut e and is provided with a slot e sothat the distance between the brackets may be adjusted.

F are two eccentrics j ournaled in the brackets E, and provided withflanges f on one side for retaining them in position; and G is a rodsecured to the said eccentrics and extending between them.

H are tapering hooks having flattened sides, which project from the rodor bar G and engage with the portions of the eyes D which projectthrough the slots. The hooks H also bear against the bar C.

I is an operating-lever secured to the middle part of the rod G, and z'is a cam also secured to the middle part of the rod. When the eccentricsare turned so that the hooks H engage with the eyes and the slotted barC, the cam bears against the middle part of the bar C and prevents itfrom springing. When the lever I is moved in the direction of the arrowin Fig. 3, the pointed ends of the hooks enter the eyes and operate aswedges. The curved inner parts 2 of the hooks may then draw the eyesthrough the slots, or the outer parts 3 of the hooks may thrust againstthe bar C, according to the exact adjustment and proportion of theparts. The large surfaces of the eccentrics alord great frictionalresistance, so that the lever I cannot slip back accidentally. The wiresare then gripped tightly between the bars B and C, and the device isself-locking. When the hooks are withdrawn from the eyes the wires arereleased.

K is a flexible connection or sling secured to one side of the bar B.The wire tightening or stretching apparatus is connected to this sling,and the clamping-bars are pulled in the direction of the arrow in Fi l,so that all the wires are stretched simultaneously.

What we claim is:

l. In a clamp for fence-wires, the combination, with two clampin -barsfor engaging the wire, one of the said bars being provided with slotsand the other bar being provided with eyes which project from the slots;of bearing-brackets secured to the slotted clamping-bar, a rod providedwith eccentrics on its ends which are journaled in the said brackets,hooks projecting from the said rod and engaging with the eyes and theslotted bar, and means for turning the said rod and its eccentrics intheir bearings.

2. In a clamp for fence-wires, the combination, with two clamping-barsfor engaging the wires, one of the said bars being provided with slotsand the other bar being provided with eyes which project from the slots;of bearing-brackets secured to the slotted clamping-bar, a rod providedwith eocentrcs' on its ends which aie journaled In testimony whereof Weax oul` signun the said bl'ckts, a aln Cecurded to the tures, n presenceof two witnesses.
